The answer is yes and yes
The earplugs retain the shape, but I usually end up "spreading" them again, partly because I forget which is right/left, or I squish them in my pocket, or it's Canada and it's cold and I have to soften them before placing them in, etc.
@ Deeve, in town I keep the plugs a bit off, otherwise it's like living in a bubble...
